Letters Patent No. 110,342, dated December 20, 1870.

IMPROVEMENT IN PENS.

The Schedule referred to in these Letters Patent and making parl: o the same.

To all 'wh-om it may concern:

Be it known that I, RICHARD H. CHINN, of the city of \Vashington and District of Columbia, have invented a new and useful improved fruitig-Pen and-Pneumatic 1enholde1'; and I do hereby declare the following to be an exact description thereof, refercnce being had to th'e accompanying drawing and to the'lcttcrs of reference marked thereon making apart of this specification, in which- Figure 1 represents the cylinder of the pcnfholder. Figure 2 represent-s the interior devices of the pen-holder,- partly in section, with the pen at the,

end.

Figure 3 shows the one side, that is, the wider side of the pen.

Figure 4 shows the opposite and wide side ofthe pen.

Figure 5 shows the narrow side of the pcn..

r Figure 6 shows the opposite narrow side of the pen. l I

Figure 47 shows how the pen maybe in two pieces or plates, attached to the end of the holder, and tit ting against a shoulder on the outside, so that the ink may low inside wit-hout hindrance to the point of the pen; the plates may be held and tightened by a ring encircling them securely to the holder.

/Figure S-shows the-cxtreme point of the pen, by which alfine or small hand is written.'

Figure 9 shows the opposite side, by which afrce or fancy hand niaypbe written, shading the letters sidewise.

Figure 10 shows that by using the at side or -widtli of the pen a larger or regular hand can be I written.

` Figure 11 shows that the opposite tlat side of the end or point of' Vthe pen writes a heavy and large hand, that is most useful for indorsing or directing large sized envelopes or packages.

The nature of my invcntioucousists in the fourpointed or sided pen, two of the sides being stitl, 'and the other two, Ior flat sides,.being elastic, so as to produce four different sizes or characters of writing.

i he pen can be attached tothe end ofthe o'rdif narypen-holde r, or to atountainv pen-holder, and my' holder consists iu a nat spring fastened on' the inside of the cylinder, operated upon by a center rod or piston forl supplying the holder and pen with a suflicient quantity ot' inlr. Y y

The object of my' invention is -to produce a pen suitable ihr different hands, either a light, uniform, or

heavy hand, andto housed-as a tbuntain-pen or on a plain handle.

the opposite point.

4 A represents the outside cylinderef the ink-holder, with au aperture, B, at the side, and a circular' head, C, with an aperture, D, for the piston-rod to move in.

Eis a fiat spring, with a valve on the one end that operates so as to open or Iclose the aperture B.

G is a gum-elastic ring, that is tted upon the spring E and fills up the cylinder near its center, to prevent any ink from passing further back.

H is an upright plate, fastened upon the top of the spring E, against which the piston-rod J is pressed,

so as to press the end of the spring downward and lower the valve from the aperture B.

The valve K is of India rubber, with a circular knobvto close the aperture or open it when the holder is to be replenished with ink.4 Y

At the top of the opposite end of spring E is another India-rubber ring, L, that v:assists in vheepinglthe upper end of the holder .air-tight and prevents any ink from passing out beyond it.

.lhe lpiston J passes through the head C, in-the center` of4v which is a small spiral spring-P, to aid the piston in reeoiling after it has been pressed down by the finger at the button Mat topnntil the valves B and K are opened to receive the ink when the peu is dipped into the iukstand, and when the finger is withdrawn from the button. M the springvalve K closes the apert-ure B and allows no 'ink to escape but in a direct tiow from the point of the pen. .i

A thin tongue, N, may be used'between the `sides of the pen to assist and regulatethc low of ink if doc med necessary.

I number each side of my pen 1, 2, and 4, and 4 when I 'wish to write a fine, small hand, I use the point, as shown at tiff. 8, and the writing is uniform, all of one style, without any heavyor shaded lines, and without regard to the pressure-upon the pen, as the point is stiff and the"writing always the same.

v lo write an ornamental hand I use the opposite corner of thepoint Yof the peu, as shown at lig. 9, that is v`slightly rounding, and as the pen is writing it makes its own heavy or shaded lines, although -the point is sti", the left-#hand point projecting beyond lo write a plain land regular handLthe 11p-stroke fine and the down-stroke heavier, I use .t-he ilat side of the pen, that is elastic with the point tothe right, as shown at g. 11.f le

The heavy hand, as 'shown at fie. 11, is 'written free and rapid, the rounding side being to the right as the pen is moved npward, and it cannot catch in the paperyaud as its ilat side'is also elastic, the

`pressure of the lmnd gives a, broad and even down- Ward stroke to the pen, the whole width of the point ifreqnired. Y

Vhat I claim as my invention, and desire to seeure by Letters Patent, is- A 1. The four-sided pen, Nos. 1, 2, 3, and 4, having two stiff points and two elastic points, togbe used with or without a. fountainha,ndle, as herein described, and for theI purposes set forth.

42. The fiat spring E, valves K and B, flange H, piston J, rubber rings G vand L, when used, arranged, :ind operating in a cylinder A its :t fountain pen-holder, in combination with my four-sided pen, as herein described, and for the purposes set forth.
